To all whom it may concern: 7

Be it known that we, ANDREW PooL and RALPH KAAN, citizens of the United States, residing at Indiana Harbor, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Smoke and Dust Consumers; and we do declare the following to be a full, clear, and

exactrdescription of the invention, such as will enable others skilled in the art to which.

it appertains to make and use the same.

This invention relates to improvements in smoke and dust consumers which may be bined scraper and conveyer within this dust catcher for carrying the dust to a suitable opening in the bottom of the catcher from which a discharge pipe leads.

With the above objects in view, our invention resides in the novel features of construction which will be hereinafter more particularly described and claimed and shown in the drawings wherein:

Figure 1 represents a side elevation of the 1 upper portion of a smoke stack showing, our improved consumer applied thereto; Fig. '2 is a central vertical longitudinal section taken on the line 2+2 of Fig. 1, and Figs. 3 and 4 are respectively transverse sections taken on the lines 33 and 4.l of Fig. 2.

In the drawings, our invention is shown applied to the usual smoke stack 1 by means A of brackets 2. v r

The invention comprises a hood 3 having a top 4 and side walls 5 which depend slightly below the top of the smoke stack as shown in Fig. 2. This hood is substantially cylindrical, the top 4; thereof being flat and having depending from its inner face an inverted conical-shaped deflector 6 substantially the diameter of the smoke stack, the apex of said deflector extending downwardly to about the top of the stack 1 as shown.

Anadditional deflector 7 is mounted within the hood 3 by the brackets 2, said deflector being substantially cylindrical inshape with open ends. This deflector 7 is spaced from and parallel to. the vwall 5 of the hood,

and spaced from'the stack 1; the upper edge of the deflector 7 is also spaced from the top iof the hood,while its lower edge is in the plane of the top of the smoke stack. From the foregoing, it willbe seen that the smoke passing from the-stack is deflected by the conical-shaped deflector'6 toward the wall 5 of the hood, but the deflector 7 guides the same upwardly toward the top 4, from which it .passes downwardly between'the wall 5 .and theouter'side of the deflector '7, and from this passage way between thewall of the hood and the; deflector 7 the light particles .of smoke pass upwardly around the lower edge of the wall 5and escape. The

passage of the smoke from the stack l'to.

the hood is indicated by the arrows In order to precipitate the heavy particlesof dust from the volume of-smoke which issues from the stack, we provide a substan tially circular spray pipe8 which preferably lies on the upper edge of the deflector 7, water'being fed 'to this spray pipe from the supply-pipe 9 which leadsup the side of the stack from any suitable source of supply. The holes in this pipe 8 extend transversely therethrough in a horizontal-plane, thus causingthe water to spray outwardly at right angles to the direction of the course 7 of the smoke.

Thus the smoke is forced to pass through the water twice on its way from the stack to the outer atmosphere.

The precipitated particles of dust and cinders are caught in a dust pan 10 which surrounds the stack 1 at a considerable distance below the lower edge of the hood.

This pan 10 has a bottom 11 having an open-' ing 12 therein to allow the accumulated dust and water to pass through a discharge pipe 13 which leads down theside of the stack 1 to a suitable receptacle. The top seat for a ring llhaving gear teeth 15 on its outer edge which are adapted to intermesh with the teeth of a spur gear 16. The gear 16 is mounted on a suitable shaft 17 driven by any preferred means.

the pan 10 is provided with a plurality of scrapers 18 which extend inwardly from said ring to the inner 'side of the pan.

The inner. side of the ring 14 which projects within "edge of the outer side of the pan forms a I These scrapers collect the dust and water which drops from the hood 3 and convey them to the 'opening'12 in the bottom of the pan, it being obvious that the ring 14 upon which the scrapers aremounted is caused to rotate by rotation of the spur gear 16. \Vhile we have shown the hood 3 and the deflector 7 as mounted on the upper end of the stack 1, by the suitably arranged brackets 2, it is obvious that separate brackets may be provided for mounting each of them separately, or that the deflector? could be fixed within the hood 3 by any preferred means.

While describing the elements best adapted for performing the operation of the smoke consumer, it is obvious that various changes inthe general arrangement of this hood. and its pan may be resorted to-without departing from the spirit or sacrificing any of the principles .of this invention.

lVe claim as our invention:

1. The combination with a smoke stack; of a hood over said stack and spaced therefrom, said hood being closed at its top and i open at its bottom, the lower edge of the wall thereof being extended below the top of said stack, a substantially cylindrical, open-ended deflector within said hood and spaced from the top and side walls thereof,

whereby smoke from the stack is deflected upwardly and then downwardly and out the open bottom of said hood, a water spray pipe on the upper edge of said deflector to spray the water both inwardly and outwardly in a substantially horizontal plane, thereby causing the smoke to pass twice through the water during its passage from i the stack to the outer atmosphere.

2. The combination with. a smoke stack; of a hood disposed thereabove, said hood Copies of this patent may be obtained for five cents each, by addressing the Commissioner ofPa'tents being closed at its top and open at its bot tom, whereby the smoke is deflected downwardly, a water'spray pipe therein, a dust.

pan disposed around said stack below said open-bottomed hood. and having an opening 1n its bottom, said pan being substantially U-shaped in cross section with a fiat bottom, a plurality of scrapers in said pan to convey the dust deposited therein :tothe discharge opening, the straight edges of said scrapers being movable over the flat:

bottom of said pan, a ringfseated on one of the upper edges of said pan and carrying the scrapers, said scrapers being sub stantially the width of the pan tomaintam the rmg in operative position, and means for revolving said ring to move the scrapers.

3. The combination with a smoke stack; of a hood over said stack and spaced therebeing extended below the top of the stack, a substantially cylindrical open ended deflector within said hood and spaced from the top and side Walls thereof, a water spray pipe on the upper edge of said deflector, an

additional inverted cone-shaped deflector ing witnesses.
